on 02017-01-14apparently #APL, R, Matlab, #Numpy, etc., are now all part of a new field called "array programming" that started in 2013. Keynoted by Morten Kromberg from Dyalog. #HPC focus.
on 02016-06-28“Seaborn is a library for making attractive and informative #statistics #graphics in #Python. It is built on top of matplotlib and tightly integrated with the PyData stack, including support for #numpy and #pandas data structures and statistical routines from scipy and statsmodels.”

#Pandas provides an efficient #EMA for #numpy.
